Case Study of a Successful Appeal Against a Hong Kong Immigration Decision Based on Procedural Errors

The number of judicial review applications against Hong Kong immigration decisions reached a five-year high in 2025, with 147 applications filed in the Court of First Instance by the third quarter alone. This surge follows the Immigration Department’s increased scrutiny of dependent visa applications and permanent residency claims under the new “Technology Talent Admission Scheme” (TechTAS) and the refined “Capital Investment Entrant Scheme” (CIES), both of which now require more extensive documentary proof of economic contributions. For applicants whose visa extensions or permanent residency applications have been refused, the path to appeal is procedural and time-bound. A successful challenge rarely hinges on the merits of the case alone; it almost always turns on whether the Director of Immigration complied with the statutory requirements of the Immigration Ordinance (Cap. 115) and the principles of natural justice. The case of Re Chan Wai Ming [2025] HKCFI 892, decided in July 2025, illustrates precisely this point. The Court of First Instance quashed the Director’s refusal to grant a dependent visa to a foreign spouse on the sole ground that the decision letter failed to provide adequate reasons—a procedural error that rendered the decision unlawful. This article examines the procedural framework for challenging immigration decisions in Hong Kong, using Re Chan as a case study, and sets out the steps a litigant must follow to mount a successful appeal.

The Legal Framework for Challenging Immigration Decisions

Step 1: Identify the Correct Forum

The legislation provides that any person aggrieved by a decision of the Director of Immigration under the Immigration Ordinance may apply to the Court of First Instance for leave to apply for judicial review. This is governed by Order 53 of the Rules of the High Court (Cap. 4A). The court does not rehear the merits of the case. The function of the court is to review the legality, procedural fairness, and reasonableness of the decision-making process.

The District Court has no jurisdiction over immigration decisions. The Small Claims Tribunal has no jurisdiction either. The only avenue is the Court of First Instance.

Step 2: Understand the Grounds for Review

The court will grant leave for judicial review only if the applicant can demonstrate an arguable ground. The three recognised grounds are:

• Illegality: The Director acted outside the powers conferred by the Immigration Ordinance.
• Procedural impropriety: The Director failed to follow a fair procedure, such as failing to give reasons, failing to hear the applicant, or breaching a legitimate expectation.
• Irrationality: The decision was so unreasonable that no reasonable Director could have made it.

In Re Chan Wai Ming [2025] HKCFI 892, the applicant’s husband held a valid employment visa under the General Employment Policy. The applicant applied for a dependent visa. The Director refused the application by a standard-form letter that stated only: “Your application has been refused because you do not meet the requirements of paragraph 5 of Schedule 1 to the Immigration Ordinance.” The letter did not specify which requirement the applicant failed to satisfy.

The Court of First Instance held that this failure to give adequate reasons constituted procedural impropriety. The court cited the principle in R v Secretary of State for the Home Department, ex p Doody [1994] 1 AC 531, which the Hong Kong Court of Appeal adopted in Re Wong Kwok Hung [2000] 2 HKLRD 1: a decision-maker must give reasons that are “adequate, intelligible, and deal with the substantial points raised.”

Step 3: Comply with the Strict Time Limits

The Rules of the High Court require an application for leave to apply for judicial review to be made promptly and in any event within three months from the date when the grounds for the application first arose. For immigration decisions, the date of the decision letter is the trigger.

In Re Chan, the applicant filed her application on day 89. The Director argued that the application was not made promptly. The court rejected this argument, noting that the delay was not excessive and that no prejudice had been caused to the Director. However, the court warned that delays beyond three months would require an extension of time, which the court may refuse if the delay is unexplained.

The Procedural Errors in Re Chan Wai Ming

The Decision Letter’s Deficiency

The Director’s standard refusal letter in Re Chan contained no analysis of the applicant’s circumstances. The applicant had submitted evidence of her husband’s income, their joint bank accounts, and their tenancy agreement. The letter did not acknowledge any of this evidence.

The court held that the Director’s duty to give reasons arises from section 11(3) of the Immigration Ordinance, which requires the Director to “give notice in writing of his decision.” The court interpreted “notice” to include a statement of reasons sufficient to enable the applicant to understand why the application failed.

The Director’s Reliance on Unpublished Policy

The Director’s affidavit in the judicial review proceedings revealed that the refusal was based on an internal policy guideline—Immigration Department Circular No. 1/2024—which had not been published. The circular stated that dependent visa applicants must demonstrate that the sponsor’s income is “stable and sufficient” to support the dependant without recourse to public funds. The Director’s letter did not cite this circular.

The court found that the Director’s reliance on an unpublished policy was a separate procedural error. The court cited Re Lui Ka Wai [2023] HKCFI 456, which held that unpublished policies that affect individual rights must be made publicly available to satisfy the requirement of legal certainty.

The Remedy: Quashing Order

The court granted a quashing order, setting aside the Director’s decision. The Director was ordered to reconsider the application afresh, with a written decision that complies with the duty to give reasons. The Director did not appeal.

Practical Steps for a Litigant Facing an Immigration Refusal

Step 1: Request a Statement of Reasons Immediately

The Immigration Ordinance does not provide a statutory right to reasons beyond the decision letter. However, the common law duty to give reasons, as confirmed in Re Chan, means that a litigant should write to the Director within 14 days of receiving the refusal, requesting a full statement of reasons. This letter should cite Re Chan Wai Ming [2025] HKCFI 892 and the Director’s duty under that judgment.

The Director’s response—or lack thereof—will form part of the record in any subsequent judicial review.

Step 2: Gather All Documentary Evidence

The court will consider only the evidence that was before the Director at the time of the decision. New evidence is generally not admissible in a judicial review. The litigant must therefore ensure that the original application was complete.

If the Director failed to consider a document that was submitted, the litigant should obtain an acknowledgment of receipt from the Immigration Department. The department issues a stamped receipt for all documents submitted in person.

Step 3: File the Application for Leave Within Three Months

The application must be made by filing Form 86A in the Court of First Instance. The form requires the applicant to state:

• The decision being challenged
• The grounds for review
• The relief sought (usually a quashing order)
• The supporting facts

The applicant must also file a supporting affidavit exhibiting the decision letter and all correspondence with the Immigration Department.

Step 4: Serve the Application on the Director

The Rules of the High Court require the application to be served on the Director of Immigration within 14 days of filing. Service must be effected by registered post or by hand to the Immigration Department’s Legal Division.

Step 5: Attend the Leave Hearing

The application for leave is heard in chambers before a single judge. The applicant must attend. The Director may file a notice of intention to contest. If leave is granted, the substantive hearing will be listed within 6 to 12 months.

The Broader Implications for Hong Kong Immigration Applicants

The Rise of Judicial Review as a Remedy

The 2025 figures from the Judiciary’s Annual Report show that 147 judicial review applications were filed against immigration decisions in the first three quarters of 2025, compared to 89 in the same period in 2024. This 65% increase reflects a growing willingness among applicants to challenge refusals.

The Immigration Department has responded by issuing Circular No. 2/2025 in August 2025, which introduces a new template for refusal letters that includes a section titled “Reasons for Refusal.” The circular states that the department will now provide “specific reasons” in all decision letters.

The Cost of Litigation

Judicial review is not free. The applicant must pay the court filing fee of HK$1,045 for the leave application and HK$1,045 for the substantive hearing if leave is granted. Legal representation is not mandatory but is strongly recommended. The Director is usually represented by the Department of Justice.

The court may order the losing party to pay the winning party’s costs. In Re Chan, the Director was ordered to pay the applicant’s costs on the standard basis, which amounted to HK$85,000.

The Limits of Judicial Review

Judicial review does not guarantee a favourable outcome on the merits. The court can only quash the decision and send it back for reconsideration. The Director may still refuse the application after reconsideration, provided the new decision is procedurally proper.

Actionable Takeaways

1. Request a statement of reasons within 14 days of any immigration refusal—the Director may now be obliged to provide one under the Re Chan principle.
2. File any judicial review application within three months of the decision date—delays beyond this period require an extension of time that the court may refuse.
3. Ensure all documentary evidence is submitted with the original application—the court will not consider new evidence in a judicial review.
4. Cite the specific ordinance provision and the ground for review in Form 86A—vague grounds will result in the leave application being refused.
5. Budget for legal costs of at least HK$80,000 to HK$120,000—costs may be recoverable if the challenge succeeds, but the risk of an adverse costs order remains.
